An off-duty police officer was at the diner on Hudson Street between Hudson Place and Newark Street at 3:27 a.m. Saturday when he saw two Jersey City brothers punching Wheeler, who fell to the floor, reports said. The fight continued, but staff managed to pull the brothers away, reports said.

Seconds later, Wheeler, who was bleeding from the back of the head, walked over to the older brother and started another scuffle. Wheeler jabbed the man between three and five times in the stomach with a knife he was holding

in his left hand, reports said.

Notified by the off-duty cop, police officers arrived and arrested Wheeler outside the building, reports said. The knife used in the attack was found in an adjacent outdoor parking lot, police said.

The older Jersey City brother was charged with simple assault and released on a summons, reports said.

Wheeler and the brother were treated at an area hospital for their injuries.
